Title: Method of melting snow on roof
Inventor: TAKAHASHI TAKASHI
IPC: E04H9/16
Filed: 1994-12-03
Abstract: PURPOSE: To effectively remove snow at a low cost by adhering a tape-like liquid suction material (a textile cloth) of different liquid absorbency on a roof at intervals and removing the snow coverage by means of running warm water through the liquid suction material to make the snow soverage sherbet-like. CONSTITUTION: A tape-like liquid suction material 2 is adhered to the snow coverage surface l on a roof or the like at intervals using a plastic or a rubber made magnet or the like, and the snow S of the liquid suction material 2 is first melted and ran down by injecting warm water from underground or the like into the liquid suction material 2 which is provided with 2 main flow passage abundant in liquid absorbency and a sub-flow passage inferior in liquid absorbency and forming the main flow passage with plain weaved lyophilic fiber such as vinylon and the sub-flow passage with twill weaved lyophobic fiber such as tetron. Material and weaving method can be arbitrarily selected. The snow coverage is removed after making it sherbet-like, while the surface area of the snow coverage is enlarged by making it appear uneven and melting is expedited by outside air and sunrays.  Thus snow can be effectively removed.
